144153-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144153-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,5 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144153-85:
(8*1)+(7*4)+(6*4)+(5*1)+(4*5)+(3*3)+(2*8)+(1*5)=115
115 % 10 = 5
So 144153-85-5 is a valid CAS Registry Number.
